Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
177 words
A connector for removably mounting a multilead integrated circuit to a printed wiring board and providing electrical interconnection between the leads of the integrated circuit and conductive elements of the circuit board, said connector comprising: a. a housing for demountable attachment to the printed wiring board, said housing having a downwardly opening cavity formed therein into which the integrated circuit is nestingly positionable, said housing having downwardly facing bottom surfaces extending laterally from the opening of said cavity below at least an opposed pair of which the leads of the integrated circuit are transversely disposed when the integrated circuit is positioned within the cavity of said housing; and b. a plurality of dual-contact spring elements dependingly suspended from at least each of the opposed pair of bottom surfaces of said housing for electrically contacting the leads of the integrated circuit and exerting a downwardly directed force thereon when the integrated circuit is positioned within the cavity of said housing, and for electrically contacting the conductive elements of the printed circuit board when said housing is mounted thereon.
Claim 2
Dependent Claim
177 words
A connector for removably mounting a multilead integrated circuit to a printed wiring board and providing electrical interconnection between the leads of the integrated circuit and conductive elements of the circuit board, said connector comprising: a. a housing for demountable attachment to the printed wiring board, said housing having a downwardly opening cavity formed therein into which the integrated circuit is nestingly positionable, said housing having downwardly facing bottom surfaces extending laterally from the opening of said cavity below at least an opposed pair of which the leads of the integrated circuit are transversely disposed when the integrated circuit is positioned within the cavity of said housing; and b. a plurality of dual-contact spring elements dependingly suspended from at least each of the opposed pair of bottom surfaces of said housing for electrically contacting the leads of the integrated circuit and exerting a downwardly directed force thereon when the integrated circuit is positioned within the cavity of said housing, and for electrically contacting the conductive elements of the printed circuit board when said housing is mounted thereon.
Claim 3
Dependent Claim
59 words
A connector as claimed in claim 1 wherein said housing is formed of dielectric material and has a plurality of apertures positioned along the length of at least each of the opposed pair of bottom surfaces of said housing and formed to extend upwardly therefrom for dependingly suspending one of said dual-contact spring elements from each of said apertures.
Claim 4
Dependent Claim
28 words
A connector as claimed in claim 1 wherein said housing has an aperture formed therein to extend downwardly from the upper surface and open into the cavity thereof.
Claim 5
Dependent Claim
52 words
A connector as claimed in claim 1 wherein each of said dual-contact spring elements is a strip of electrically conductive material formed into a substantially semicircular configuration to provide a first contact end and a second contact end and having a radially extending loop substantially intermediate the first and second contact ends.
Claim 6
Dependent Claim
69 words
A connector as claimed in claim 1 wherein each of said dual-contact spring elements is a strip of electrically conductive material formed into a semicircular configuration to provide a first contact end and a second contact end between which a radially Extending protrusion is provided, said protrusion being insertable within an upwardly extending aperture formed in the bottom surface of said housing for mounting said dual-contact spring element thereto.
Claim 7
Dependent Claim
48 words
A connector as claimed in claim 5 wherein said radially extending protrusion comprises a loop formed in said strip of material, said loop being of sufficient elongation to extend upwardly from the bottom surface of said housing and be exposed adjacent to the upper surface of said housing.
Claim 8
Dependent Claim
46 words
A connector as claimed in claim 5 wherein said radially extending protrusion comprises a wire-wrapping pin attached to said strip of material and of elongated dimension to extend upwardly from the bottom surface of said housing to a location above the upper surface of said housing.
Claim 9
Dependent Claim
34 words
A connector as claimed in claim 1 wherein said housing is provided with a plurality of parallel elongated slots formed in the upper surface thereof and extending downwardly into the cavity of said housing.
Claim 10
Dependent Claim
44 words
A connector as claimed in claim 1 wherein said housing is provided with an endless depending lip integrally formed on the outermost edges of the bottom surfaces of said housing, said depending lip having a lowermost end upon which a sealing gasket is affixed.
Claim 11
Dependent Claim
62 words
A connector as claimed in claim 1 wherein said housing is formed of metallic material and at least the opposed pair of the bottom surfaces thereof are each formed with an elongated downwardly opening channel for receiving an elongated strip of insulative material from which a plurality of said dual-contact spring elements are dependingly suspended in spaced increments along the length thereof.
